Specification of Letters Patent.

Patented June 30, 1914.

Application filed. November 1, 1913. Serial No. 798,617.

To all whom it may concern:

Be it known that I, ALBERT Sorrnnrrrr, residing at Newark, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Pivoted lVindows, of which the following is a full, clear, and exact description.

My invention relates generally to windows in which the sash can be slid up and down for opening or closing the window in the usual manner, and which can also be turned on pivots so that access may be had to both sides of the sash from the inside of the building, and more particularly to the guide-bars for such windows. As is well known to those skilled in the art, when windows of this class are being installed, serious binding of the guide-bars results if the window stops are not in proper spaced relation thereto. These guide-bars are often made to stick or bind by the paint which is placed on the window parts after the stops have been secured in permanent position.

The general object of my device has been to overcome this disadvantage and inconvenience, and I have accomplished this by providing a guide-bar having a narrow spacing ridge, which, when the window is first turned on its pivots breaks and is detached from the guide-bar, thus leaving the required amount of clearance space.

Reference is to be had to the accompanying drawings forming part of this specification, in which like characters of reference indicate like parts, throughout the several views, of which:

Figure 1 shows a front elevation of a window frame, to which my invention is applied. Fig. 2 is a sectional elevation of the same taken on line 2--2 of Fig. 1. Fi 3 is an enlarged fragmentary sectional view of the guide-bar with its ridge and is taken on line 3-3 of Fig. 1. Fig. 4c is an enlarged fragmentary perspective view of one of the guide-bars of my window provided with a spacing ridge. Fi 5 is an enlarged fragmentary sectional view taken on line 3-3 of Fig. 1 and shows a modification of my invention in which the spacing ridge is provided on the window stop. In the drawings. 5 represents the window casing which is of the usual construction, and 6 and 7 the upper and lower window sashes, respectively. These window sashes are pivoted at or near their centers to the guide-bars 8 and are slidable up and down in guidcways provided in the window casing as usual. Each guidebar 8, upon the surface which contacts with the window sash, is provided with an irregularly curved surface which co-acts with a substantially similarly curved surface on the edge of the window sash, as is customary in window constructions of this type. Preferably, the face 9 of each guide-bar, adjacent to the window casing, is inclined somewhat (see Fig. 3) so that its face 9 makes an angle with the face 15, which is less than a right angle, and is provided at the edge 10 with a thin longitudinally extending spacing ridge 11. The height of this ridge above the surface 12 of the guide-bar is such as to give proper clearance space between the guidebar and the stop 13 of the window.

In the modification shown in Fig. 5, I carry out my invention by providing a thin longitudinally extending spacing ridge 11 on the window stop 13, which is arranged to bear against the curved surface 12 of the guide-bar 9.

When windows provided with my guide bars are installed, the window stop 13 or 13 is pl accd up against the guide-bar 8 with the spacing ridge 11 or 11 therebetween, whereupon the stop is secured in place in the usual manner. WVhen the window sash is turned upon its pivots, the gl'iide-bar 8 will be given a lateral motion between the stops. The guide-bar will. also be slightly oscillated around the corner 14; as a center, and as the face 9 is inclined, this oscillating motion will cause the narrow ridge 11 or 11 to be wedged in between the stop and guide-bar and to be thereby broken off and severed from the same. After this ridge is once broken away the guide-bars will always have a predetermined amount of clearance equal to the height of the ridge before being broken off. It will be obvious that by providing these narrow ridges on the guidc-bars, the stops may be set in uniform and spaced relation with the guide-bars. and thus obviate any binding of the same due to poor or careless workmanship in fitting the window sashes, or of binding caused by paint.

Having thus described my invention, what I claim is:

1. The combination with a window frame provided with window stops and a pivotally mounted sash which clears said stops, of a guide bar capable of turning transversely between said stops and bearing against said sash, and a spacing ridge between one of the edges of said guide-bar and one of said stops.

2. The combination with a window frame provided with window stops and a pivotally mounted sash which clears said stops, of a guide-bar capable of turning transversely between said stops and bearing against said sash, said guide-bar being provided on one of its edges which face said stops with a spacing ridge.

3. The combination with a window frame provided with window stops and a pivotally mounted sash which clears said stops, of a guide-bar capable of turning transversely between said stops and bearing against said sash, said guide-bar being provided on one of its edges which face said stops with a spacing ridge, and having its face, which is opposite the sash, inclined toward said spacing ridge.

4. The combination with a window frame provided with window stops and a pivotally mounted sash which clears said stops, of a guide-bar capable of moving laterally and turning transversely between said stops and bearing against said sash, said guide-bar being provided on one of its edges, which face said stops, with a spacing ridge.

5. The combination with a window frame provided with window stops and a pivotally mounted sash which clears said stops, of a guide-bar capable of moving laterally and turning transversely between said stops and bearing against said sash, said guide-bar being provided on one of its edges, which face said stops, with a spacing ridge, and having its face, which is opposite the sash, inclined toward said spacing ridge.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
